Figure 3-5 System Status Screen
This section provides pictures and details of the Exciter Status screen, shown in Figure 3-5,
and its sub screens. The sub screens give the status of selected control areas or PC boards,
some of the sub screens include diagnostics screens.
If the Diagnostics Setup on the Exciter System Setup screen is locked, all diagnostics
functions will be locked, and their various screen selection values will be greyed out.
3.4.1
System Status Screen
Refer to Figure 3-5. The System Status screen serves two purposes. First, it provides a
general status of five items, and secondly it provides access to many sub screens which
give additional status information about selected circuit boards within the exciter.
Five small boxes are displayed within the System Status screen. These boxes represent
circuit boards or control areas within the exciter, see names in Table 3-1. The general status
of each section (OK or FAULT) is displayed to the right of each box. Touching any of the
boxes brings up the status screen for that selection.
Five hardware switches on the exciter front panel (to the immediate right of the LCD
display) provide short cuts which leads directly to the five status areas listed in Table 3-1.
